rename core to litcofee files
work in progress on refactoring to singleton approach

  - include consistent markdown headers
  - remove requirements on globally defined variables
  - defined singleton pattern
  - converted to coffeescript class statements
still work in progress, but is somewhat functional now

actually pretty cool how easy it was to incrementally add plugins back in
move loading of global libraries into celestrium
simplify global plugin management
ensure global library dependencies are respected
correct keylistener
working dimensionality slider
improve link strength histogram filtering
add hotkeys
move back to coffeescript
un-indent to convert back to coffee
convert histogram to link strength cdf
create abstract data provider
now uses inverse cdf
move to variably smoothed pdf of link strengths
add dimensionality stat
turn off node profile by default
small improvements
cleanup
